environments which have falling water such as rain.
Read and follow "Electric Shock Warnings" in the
Safety section if welding must be performed under
electrically hazardous conditions such as welding in
wet areas or on or in the workpiece.
• The Precision TIG 225 must be located where there
is free circulation of clean air such that air move-
ment in and out the back air vents will not be
restricted.
• Dirt and dust that can be drawn into the Precision
TIG 225 should be kept to a minimum. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdown.
